Can I replace the manifold gaskets without pulling the ypipe? Been a while since I've done a EA, I know you can on EJs. Now that the head has no oil on it, I can see a exhaust stain forming on the passenger side, so need to replace them.

Worst case, you might have to remove the support bolt that hangs it from the transmission.

I’ve done it on XTs which are EA vehicles. I’d use OEM gaskets.

if all the exhaust nuts are rust welded onto the studs, and pull the studs out of the engine, it’ll be easy. Lol. 

Possibly burning out due to threads in head needing first aid. All success in removing studs, sliding new gaskets in can come undone when studs won't tighten - pull it all out again to repair thread
